The new PFM3000 from TTi, represented in Australia by Emona Instruments , is a European built hand-held frequency counter, which can measure signals from below 3Hz to above 3GHz.

The PFM3000 hand-held frequency counter is compact and incorporates advanced features. It uses the ‘reciprocal counting’ measurement technique to achieve high measurement resolution at all frequencies. The system yields up to 8 digits of resolution per second of measurement time and can resolve low frequencies to 0.001mHz (0.000001Hz).

Two measurement ranges are provided. Range A covers from below 3Hz to above 125MHz through a high impedance input. Range B covers from below 80MHz to above 3000MHz through a 50 Ohm input. Sensitivity is better than 15mV across the range, rising to 25mV at 2.5GHz and 50mV at 3GHz.

Period measurement is provided for signals in the range of 8ns to 330ms. A selectable low-pass filter is provided to reduce the noise on lower frequency signals. A hold key allows readings to be frozen on the display whenever required.

Low power consumption circuitry can ensure a long battery life and a ‘push to measure’ facility is also incorporated. This provides an immediate reading on the press of a key followed by an automatic power down after 15 seconds, thus ensuring a maximum battery life when continuous signal monitoring is not required.

The PFM3000 hand-held frequency counter is housed in a robust ABS case measuring 81 x 173 x 30mm and weighing less than 200g. A large LCD display of high contrast is incorporated with 11.5mm high characters. The LCD display incorporates 15 annunciators covering measurement function, measurement time, units, overflow, trigger activity and low battery.
